Evaluating synchronization on shared address space multiprocessors: mehtodology and performance

摘要

Synchronization ins an area that exhibits rich hardware-software interactons n multiprocessors.It was studied extensively using microbenchmarks a decade ago.However,its performan eimplications are not wwell understood on modern systems or on real applications.We study the impact of synchronization primi=tives and algorithms on a odern,64-processor,hardware-coherent shared address space multiprocessor: the SGI Origin 2000.In addition to the actual results on a modern system,we examine the key methodological issues in studying synchronization,for both microbenchmarks and applications.
